This is the Leo Triplet — a trio of galaxies located in Leo about 30 million light years away. Before succumbing to the 25 degree temps and falling asleep in my car, I told my computer to run an automated time lapse of this target. I got 38 minutes of usable data before my laptop died, and that’s what you see here.
NGC 3628, located at top right, is particularly interesting to me. Does it look familiar? Just like the Milky Way, it too is a spiral galaxy whose core is obscured by dust lanes that we’re seeing edge on. A lot of folks don’t really know what they’re looking at when we see the Milky Way. I think this really helps put it into perspective.
